HARRY NORTON MARVIN, OF CANASTOTA, NEIV YORK, ASSIGNOR TO THE AMERICAN MUTOSOOPE COMPANY, OF NEIV YORK, N. Y.

MUTOSCOPE.

SPECIFICATION forming part of Letters Patent No. 584,228, dated June 8, 1897. Application filed November 14, 1895. Serial No. 568,897. (No model.)

To all whom, it may concern:

Be it known that I, HARRY NORTON MAR- VIN, of Canastota, in the county of Madison, in the State of New York, have invented new and useful Improvements in Mutoscopes, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the construction and operation of a mutoscope.

My object is to produce a device upon which picture-cards are adapted to be mounted, so arranged and operated that by successively and quickly bringing the pictures upon the 5 cards into the line of vision they will exhibit the changing positions of the body of the figures and apparently reproduce to the eyes the movements of the performers; and to that end my invention consists in the several new and so novel features and combination of parts hereinafter described and which are specifically set forth in the claim hereunto annexed. It is constructed as follows, reference beinghad to the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of the mutoscope and means for successively and quickly bringing the figures upon the cards into the line of vision. Fig. 2 is a top planview of the device complete.

A is a cylinder constructed substantially as shown, having an opening a upon one edgeand B is a spool having slotways therein, in which the picture-cards b are adapted to be mounted, as shown in Fig. 1.

c is an arbor or axle journaled in the sides of the cylinder and upon which the spool B is mounted and adapted to rotate, as indicated by the arrows. Upon one edge of the cylinder is mounted a pipe 0, ending in a flattube with a small mouth d, as showm, and c is a pin mounted in the edge of the cylinder adapted to retard the upper ends of the cards, as shown.

My invention is operated as follows I place an end of the tube 0 to the mouth and blow into it or otherwise force air through said tube, which passes out of the flat end into the cylinder, as indicated by the arrows, onto the cards and causes the spool and cards to rotate rapidly, being momentarily retarded by the pin or stud c. It will thus be observed that the cards, being retarded by the stud, will part opposite the opening in the cylinder and as they successively and rapidly slip or snap past the stud will reveal the pictures in rotation, so as to produce the desired result.

I am aware that devices of the character shown in Figs. 1 and 2 have heretofore been constructed by Herman Casler, of Syracuse, New York, as shown in his patent dated November 5, 1895, No. 54.9,300, and by IV. C. Farnuin, dated October 1, 1895, No. 547,000, but in each of these devices the cards have been driven forward by force applied to the central arbor and the quick snapping mo tion of the cards produced by the elasticity of the card itself or by a resilient card mounted adjacent thereto for the purpose of lending elasticity to the picture-card, but in this invention I drive the cards around and produce the desired eliect by external force not applied to the arbor, by which force I am enabled to successively bringinto the line of vision bya blast of air applied to the face of the card itself and do not depend upon the elasticity of the card or its support for the quick motion necessary to bring the cards into view.

The advantages of my invention consist in the cheap and simple application of power to rotate the spool and in the fact that power is applied at the nearest possible approximation to the point where the resistance is encountered. Furthermore, the point of application of the power and the agency employeda blast of airena-ble it to perform a new function, that of assisting the resiliency of the card by directly and bodily lifting the card over after it has been released from under the retaining pin or stud. By reason of this new function a much thinner, less resilient, and 0 cheaper card may be used and a greater num ber of cards set about an arbor of given diameter.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

In a mutoscopc the combination of acylinder having an opening at one side thereof, a

In Witness whereof I have hereunto set my hand on this 9th day of November, 1895.
